How can I turn off 3G and use just 2G? SOLVED

Hey everyone,
I've had my Galaxy a few days now and I noticed there's no obvious option to turn off 3G like there was on my old Topaz.
Does anyone know if it's possible to turn off 3G (not data connection, I still want to use 2G) to save battery life.

Go to settings > wireless and networks > mobile networks > use only 2g. The option is there.

Erm, that option isn't there, all it says in mobile networks is:
Data Roaming
Access Point Names
Network Mode (this is only GSM/WCDMA switching)
Network Operator
I bought my phone as handset only so there's no branding and is rooted (option wasn't there before rooting either).
Can anyone help? Is there an app that can help?

My options changed when I upgraded to the newest firmware available in Australia. GSM is 2G and WSDM is 3G.

I downloaded an app/widget from the market called DCSwitch ... it allowed me to disable/enable my HSDPA radio with the touch of single button on my homescreen.

[q] help needed no 3g or mobile internet

After flashing to froyo i now have no 3g or mobile internet ,im on vodafone ireland and just wanted to know if anybody knows which csc to reflash to. Before anyone suggests i check my apn settings i already got them off vodafone sent to my phone but it still says in menu -about phone-status-mobile network state=disconnected.
Can anybody help cos at the mo i can only use wifi evev though i paid for a 2gb data allowance.

did you create the APN settings?
it doesn't get sent, it doesn't program itself automatically
you need to make it yourself

Yeah I got the settings as a configuration message and it installed the vodafone settings but it won't show the upload download arrows anymore.

here is one easy way to confirm if the settings work
http://forum.xda-developers.com/showpost.php?p=8124344&postcount=45
install the APN on/off switch
then set it to ON, tried turning it off/on/off/on see if it works

you can also try this
http://forum.xda-developers.com/showthread.php?t=789039&highlight=*#0011#
it should show if you are connected or not to any of those bands

http://forum.xda-developers.com/showthread.php?t=789039&highlight=*#0011#

you can not get *#0011# to work on the dial pad?

Did you find your APN settings off the net?

what does it say, what information?

hi there. anyone successfully fixed this? for two days now I cannot get any 3g signal. it just stopped working at some point. thinking it must've been an app or something, i did a complete reflash of the XWJPA firmware. that unfortunately did not help at all.
apn is CORRECT, data network is enabled, no 3g....
edit: btw, this is on 3 network in reading, uk.
edit 2: disregard my post, the problem was the borked sim card. all is well now.

[Q] Help, SGS has no signal sometimes

My phone is from UK orange. my phone has great signal at home and office.
However, after I upgraded to Froyo JPO version firmware, my phone has signal in my office with 3G but has no signal at home and some other places where the 3g signal is weak or not working. This is very annoying. Please anyone can help me?
My original firmware: JP5/JP3/JP1
My current firmware: XXJPO/XXJPP/XAJPO
MY Production code: I9000HKDORA
Tonight I try to flash lots of versions from samfirmware.com but there is no signal for all firmwares.
Please can anyone help me? It seems that my current wersion does not support 2G signal???
Thanks in advance

can you check your IMEI in the phone (settings>about phone>status) and compare it with the IMEI indicated in the box (or remove teh battery and there should be a sticker at the back of teh phone with your IMEI).
Note: Also check if your APN settings are correct and complete. It might have been deleted or changed after the flash.

I have checked the imei, it is the same. The apn is orangeinternet, I think it is correct.
When I go to somewhere, the phone can be used with symbol of 3g or E or H, but at home only signal bar shown and emergency call only.

In Settings / Wireless and network / Mobile network settings / Network mode, set to GSM/WCDMA (auto mode) and see what happens

It is GSM/WCDMA (auto mode) selected.
I remember I can only choose 3G and wireless network when I just flash the FROYO JPO firmware...

It is possible that orange are working on the network. I had similar issues a few weeks ago (I'm in the southeast) bit is now fine. You could go see your local orange guys and ask.

But I can use this sim card on the other phone, like HTC HD2, perfectly at home. Does the SGS have such bug? I am in the southwest.

try see if you have the missing 850 band bug?

Dammed, even in the london i cannot find signal sometimes

Anyone knows where to download the orange customed firmware: I9000BVJM5/BVJM1/RAJM3?
Thank you!

Orange UK 3G problem?

Is anyone else having any problems with their data connections on orange in the UK?
I've only just noticed that i have on data connection at all.
At first i thought it was because i set my wireless lan settings to a static ip. But changing it back does not bring my 3G back.
Then i remembered i upgraded from darkys rom 9.3 to 9.4 so thought maybe it was the modem included in the update. But i just changed the modem back to zpg and still no luck.
I have data turned on in the settings, But when i go to the about screen it says disconnected.
Im sure my settings are right, and i sent a picture message this afternoon which was delivered ok.
Im at a loss as what to try next?
Anyone else have any ideas.

Panic over. Data connection is back. Although only 2G, so it looks like orange are having problems again.
Sent from my GT-I9000 using XDA Premium App

Yeah, been having the same issues too. I'm wondering if we're better turning off the data roaming I had enabled to allow me onto T-Mobile's network.

Orange and t-mobile dont share their 3G networks as of yet only the 2G.

Still having problems here.
But thankfully its the network and not my phone!

No orange 3G problems for me.

[Q] No list of network under Network Operators > Availalbe Networks

Hi,
I am using KK4 rom with Kk4 Modem on Captivate i897.
When I go into Settings > Wireless and network > Mobile networks > Network operators, it just shows Default setup which is greyd out (but it connects to my network operator just fine)
How do I get it to display the list of availalbe networks and let me select the network?
I tried google and XDA forum, and wasn't able to find much information.
The only post I've found was from Infuse forum where someone suggested that ATT has locked this function in the modem level and flashing Rogers modem will fix it for Infuse.
I flashed Rogers KH2 modem, but it is still not displaying the list of networks.

Even my SGS II has that grayed out...

I think they are greyed out on network locked phone.
Sent from my Touchpad using xda premium

Doesn't matter if the phone is locked or not, mine is unlocked and it's still greyed out. (I'm still using at&t)
And this is on an I9000 ROM/kernel/modem, at&t has nothing to do with this set up at all.
I'm sure it would be the same if i had a tmobile Sim in. Think about it, the only network you can connect to with a carrier specific Sim, is that network.

So, does this leave the door open for a universal Sim? Hmmm

Maybe it's specific to Samsung phones (or Gingerbread)?
My previous 2 Android phones (HTC Magic and HTC Legend, both were running Froyo) did allow me to manually select the network.
